SPECIFICATION forming part of Letters Patent N o. 704,999, dated July 15, 1902.

Application filed .lune 24, 1901.

T0 a/ZZ wwm/ it may concern:

Be it known that I, VWILLIAM WHITE, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have inventeda new and useful Im-V provement in Curbing and Paving, of which the following is a specication.

My invention consistsof an' improvement in curlostones and pavements, whereby a strong and durable curbstone is formed with means for preventing the grinding away of the stone.

It further consists of an improvement in pavements, whereby the cracking thereof is confined to a certain space.

It further consists of novel details of construction, all as willbe hereinafter set forth.

Figure 1 represents a perspective View of a curbstone embodyingr my invention. Fig. 2 represents a perspective View of the parts employed in forming the curbstone. Fig. 3 represents a vertical sectional view of a portion ofthe curbstone. Fig. 4 represents a perspective View of a curbstone and pavement in position, showing a portion thereof eut away. Fig. 5 represents a vertical sectional view of a curbstone and a portion of a pavement.

Similar letters of reference indicate corresponding parts in the figures.

Referring to the drawings, A designates a curbstone,having the end plates B,which are preferably formed of metal and which are provided with the slots or cut-away portions C and have on their inner faces S the anchors D and the lugs E, which project in wardly from said plates B.

F designates a rod or bar having substantially a flat face or surface and the shoulder or projection G,extending from the rear face, and whichis provided with the notches or cut-away portions H, the sides J of which are preferably inclined.

K designates tie-rods which are adapted to engage in any suitable manner with the anchors D and lock the plates together, therods F being adapted to be supported by the lugs E on the plates B, the position of the plates being as best seenin Fig. 2. The curbstone is finished by filling in between the plates B `bility and length of life with suitable asphalt, concrete, or material Serial No. 65,7447. (No model.)

which will enter the slots C and will engage with the rods and enter the notches H in the projection G, and will rest upon the said projection G, and is then curved or rounded', as at L, (seen in Fig. 5,) and when the concrete or material is hardened it will be seen that a very strong and compact curbstone is made, the bar F serving as the means ora guard at the proper place in the curb to prevent the grinding away of the concrete, owing to the contact therewith of the `wheels of vehicles, drei, it being understood that when the concrete is filled in suitable guards are employed in order to make the proper shape of the curb. By this means I am able `to makethe curbstone of any desired size, andthe same are fitted together end to end, which is also an improvement over thepresent form of curbstone where theyare formed of concrete,since the same are usually made in one piece, and should a crack occur for any reason it will extend the entire length, as a rule. In my construction this is prevented, and the duraof the curbstone are increased.

M designates tie bars or hooks, which are inserted in the curb before the same is hardened and also in the concrete N, which forms the pavement,-so that the curb and pavement arelocked together. In the preferred form of pavement I employ cement or concrete, as

. is usual, and then divide the same into blocks or sections, and by pressing thereinto a bar P, having the fiat head or surface Q, the under side R of which is rounded, as best seen in Fig. 5, said bars having openings S therein into which the concrete is adapted to enter and prevent the movement of said bars, it being understood that I employ a longer or shorter bar, as may be desired, it being further seen that by the employment of the bars P no line or depression is made in the concrete, as is now the case, and that each block is entirely separate and distinct from the other by reason of the bars P, and that by reason of the head Q on said bars edge of cementis protected.

It is by doing away with the depression that much of the cracking is obviated, for should the same crack it is limited by reason of the bars, while in the present construction IOO it will runa Very considerable distance in th pavement.

I do not desire to be limited in every instance to the exact form herein described, but desire to make such changes as will come Within the scope of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In acurbstone,plates for the ends thereof, a guard for the face thereof situated between said plates, and a flange extending therefrom adapted to be embedded in the concrete and having notches for locking the same in position.

2. In a curbstone, plates on the ends thereof, and means situated entirely between said plates for holding the same together.

3. In a curbstone, plates for the ends there-` of, a guard supported between said plates whereby the plates vof adjacent ourbstones can be placed in contact. l

4:. In a curbstone, plates for the ends thereof, a guard supported between said plates, and means between said plates and engaging therewith for locking the same together.

In a curbstone, plates for the ends thereof, anchors on the inner faces of said plates,

and tie-rods adapted to engage with said anchors to lock said plates together.

6. In a curbstone, plates for the ends thereof, means on the inner faces of said plates for locking the same together, a guard for the face of said curbstone, and lugs on the inner faces of said plates adapted to support said guard.

l 7. In a' curbstone, a concrete body, plates for the ends thereof, a guard for the face of said curbstone, having notches or recesses engaging with the concrete and locking said guard in position.

8. In a curbstone, formed of suitable material, plates for the ends thereof, anchors on said plates, rods engaging said anchors to lock said plates together, lugs on said plates, a guard supported by said lugs, and notches in said guard for locking the same in position.

9. The combination of a concrete curbstone and pavement, a plate between the same, and means for locking the curbstone and pavement together with the plate be tween.
